Abstract
The utility model belongs to the technical field of air conditioning control, particularly relates to a fault operation acousto-optic alarm device of a special vehicle air conditioner, which consists of a high voltage control switch, a lower voltage control switch, a compressor protection switch, a fan protection switch, a fault control relay, a fault alarm relay control contact and an acousto-optic alarm, wherein the high voltage control switch, the lower voltage control switch, the compressor protection switch, the fan protection switch and the fault control relay are connected in series into a line, the fault alarm relay control contact and the acousto-optic alarm are connected in series into another line, the two lines are connected in parallel, and the two ends of the formed lines A and B are connected into the power supply of a vehicle air conditioning control. The utility model has simple lines, selects materials easily, fully uses the original control line, can be realized through slightly changing, is convenient to install, can normally work in the air reaching 75 DEG C, and thereby effectively ensuring the technological production and other operation to be normally carried out.
Description
Technical field
The utility model belongs to air conditioning control technology field, is specifically related to a kind of driving special air conditioner operation troubles acoustic-optic alarm.
Background technology
The operational environment of bridge crane air conditioning and common civilian air-conditioning are very different.Its environment for use is special, and for example in the driving of lifting ladle, vibration is violent, the operating mode instability, and during the broiling summer, the condenser of air conditioner will be worked under 40 ℃～75 ℃ the high temperature and the adverse circumstances of high dust concentration.Therefore bridge crane air conditioning has some special characteristics and requirements: at first normally carry out the reliability requirement height for what guarantee to produce; Secondly, the work under bad environment of driving (high temperature and many dirt), these characteristics can produce very big influence to unit performance.Because work under bad environment, bridge crane air conditioning moves under hot environment that often failure rate is higher, the particularly driving of some wireless remotely-controlled operations, operating personnel generally shake control operation (handling the workshop as the steel-making slag) on the ground, the bridge crane air conditioning machine breaks down and is difficult in time find, in case the air-conditioning fault can not in time be found to handle, cause the electric cabin of driving temperature overtemperature, will serious harm the safe operation of driving electric equipment, therefore install additional once cover driving special air conditioner operation troubles acoustic-optic alarm and seem very necessary.
The utility model content
The purpose of this utility model is to provide a kind of driving special air conditioner operation troubles acoustic-optic alarm, this device can ambient temperature up to 75 ℃ air in operate as normal, thereby guarantee normally carrying out of explained hereafter and other operations effectively.
The driving special air conditioner operation troubles acoustic-optic alarm that the utility model proposes; by dual pressure control switch 1; low-voltage control switch 2; compressor protection switch 3; blower fan protection switch 4; Fault Control relay 5; fault alarm relay control contact 6 and audible-visual annunciator 7 are formed; wherein dual pressure control switch 1; low-voltage control switch 2; compressor protection switch 3; blower fan protection switch 4 and Fault Control relay 5 are serially connected in a circuit successively; after fault alarm relay control contact 6 and audible-visual annunciator 7 are serially connected in another circuit; two circuit parallel connections, and the circuit after the parallel connection two terminates in the bridge crane air conditioning control power supply.
The beneficial effects of the utility model are:
1, circuit is simple, and selection is easy;
2, made full use of former control circuit, done slightly to change and to realize;
3, easy for installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 is dual pressure control switch, and 2 is low-voltage control switch, and 3 is the compressor protection switch, and 4 is the blower fan protection switch, and 5 is the Fault Control relay, and 6 are fault alarm relay control contact, and 7 is audible-visual annunciator.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1:
As shown in Figure 1; this device is made up of dual pressure control switch 1, low-voltage control switch 2, compressor protection switch 3, blower fan protection switch 4, Fault Control relay 5, fault alarm relay control contact 6, audible-visual annunciator 7; dual pressure control switch 1 model is JBG2; low-voltage control switch 2 models are JA72; compressor protection switch 3 models are LR2P337; blower fan protection switch 4 models are LR2P337, and Fault Control relay 5 models are CLK-26J-96, and audible-visual annunciator 7 models are BC-8T.Wherein: dual pressure control switch 1, low-voltage control switch 2, compressor protection switch 3, blower fan protection switch 4 and Fault Control relay 5 are serially connected in a circuit; after fault alarm relay control contact 6 and audible-visual annunciator 7 are serially connected in another circuit; two circuit parallel connections, and the circuit A, the B two that form terminate in the bridge crane air conditioning control power supply.
The course of work of the present utility model is as follows:
The utility model circuit A, B two terminate in the bridge crane air conditioning control power supply; be in normally off under dual pressure control switch 1, low-voltage control switch 2, compressor protection switch 3, blower fan protection switch 4, the non-failure conditions; connect Fault Control relay 5; Fault Control relay 5 disconnects fault alarm relay control electric shock 6, and air-conditioning is in normal operation state of a control.After the operation starting; when system's mesohigh control switch 1, low-voltage control switch 2, compressor protection switch 3,4 any one actions of breaking down of blower fan protection switch; Fault Control relay 5 dead electricity; Fault Control relay 5 disconnects fault alarm relay control electric shock 6 and becomes closure; audible-visual annunciator 7 gets electric work at this moment, thereby sends the sound and light alarm signal.
